FIELD OF THE INVENTION

Aspects of the present invention relate to portable electronic vaporizing devices for use with vaporizable products.

BACKGROUND

Electronic vaporizers are commonplace and are generally utilized for the purpose of aroma and/or inhalation therapy. In this regard, vaporizers heat a substance, herbs for example, such as tobacco, cannabis, lavender, chamomile, and many other types of plant material. The vaporizer may work by heating the substance through the use of direct heat or the use of hot air. There are three common ways of heating the substance. The first is thermal conduction where the substance is set directly on a heating element such as a ceramic or metal plate. The second is thermal radiation in which light is used to heat the substance. The third is convection where hot air is passed over the substance. Yet another suitable mechanism for vaporizing a substance may be via inductive heating.

At lower levels of heat, vapors extracted from substances such as vegetable materials are mainly aroma therapeutic (inactive fragrance) and do not usually contain the active ingredients of the substance. Without the active ingredients being present, there is no physiological reaction. At higher levels of heat, active ingredients will be increasingly included in the vapor given off during heating. Usually, aromatic vapors have already been released and are not always present at the higher heat levels. With some substances, such as cannabis, active ingredients appear at different levels of heat.

After the substance is heated a mist or vapor containing some aspect of the substance is released and either enjoyed as an aromatic or inhaled to obtain a physiological reaction. The warm air containing the substance product can be harsh on the throat and bronchial tubes. Accordingly, some vaporizers use a cooling down process that allows water moisture to be included in the vapor produced. These vaporizers enable the user to inhale a cool moist vapor that is relatively less harsh and irritating. Vaporizers are often preferred over traditional methods of heating or smoking substances due to the reduction of harsh side effects. Some of these side effects include inhalation of tar, carbon monoxide, and other carcinogens either directly or from second hand smoke. With many states imposing smoking bans in public areas, vaporizers have become popular substitutes.

Accordingly, there is a need for improved vaporizers that provide an enhanced vaporizing experience, including vaporizers with improved quality of the vapor produced for inhalation and improved ease of use.

DETAILED DESCRIPTION OF THE INVENTION

Aspects of the invention as described herein are directed to an improved portable electronic vaporizing device for the inhalation of vaporizable substances, such as aromatic substances, therapeutic substances and/or substances with physiological effects. Examples of such substances can include herbs, such as tobacco, cannabis, lavender, chamomile, and other types of plant material. In one embodiment, a vaporizable substance can comprise a cannabinoid, such as for example one or more of cannabadiol (a generally non-psychoactive therapeutic substance) and tetrahydrocannabinol (THC) (a psychoactive therapeutic substance). The vaporizable substance may in some embodiments be in the form of an oil and/or wax product comprising the vaporizable substance, e.g., as extracted from plant material containing the substance, and may optionally be provided in combination with carriers or other additives.

Referring to FIG. 1 , an embodiment of a portable electronic vaporizing device 1 is shown according to aspects of the disclosure herein. The portable electronic vaporizing device 1 comprises a removably attachable vaporization module 2 and a mouthpiece 3. The removably attachable vaporization module 2 is configured to receive a vaporizable product therein and to heat the vaporizable product to form a vapor therefrom. The mouthpiece 3 comprises an inhalation outlet 305 (depicted in FIG. 9B) where a user can inhale the vapor produced by the removably attachable vaporization module 2, optionally with water or other substances entrained therein. The mouthpiece 3 can be provided in various forms including but not limited to a pipe, or forms, and optionally with water filtration.

Referring to FIG. 2 , an embodiment of the device 1 is shown in exploded view, with the removably attachable vaporization module 2 removed from the mouthpiece 3. The removably attachable vaporization module 2 further comprises (and in FIG. 2 is shown as separated into) a vaporization assembly 4 and a base portion 5. The base portion 5 provides a gas flow connection between the vaporization assembly 4 and mouthpiece 3, to deliver the vaporized product from the vaporization assembly 4 to the mouthpiece 3 for delivery to the user via inhalation thereof. The base portion 5 can also comprise a housing for one or more components for powering and/or controlling the device 1. For example, the base may contain compartments therein for storing a power source, such as a battery, for powering elements of the device 1 such as a heating element or other heating device used in the vaporization assembly 4. In a case where the device is powered by a rechargeable battery, such as a lithium ion battery, the base portion 5 may also comprise a charging port connectable to a battery charger (not shown). The base may also have compartment doors to allow access to a battery or other components held within the housing. The base portion 5 may also house further control circuitry for controlling the device, such as to provide predetermined heating cycles or heating programs, and may also allow for user interaction with the device via control buttons and/or control interface, a display and/or lights to signal to the user, and/or other control and operation features.

In one embodiment, the mouthpiece 3 is removably attachable to the base portion 5, for example so as to allow a user to readily remove the mouthpiece for cleaning and/or replacement, as is described in further detail herein. For example, according to one embodiment, the base portion 5 and mouthpiece can be removed from one another by exerting a force on the base portion 5 that exceeds a retaining force of sealing regions (described below) that form a seal between portions of the base portion and the mouthpiece), to lift the base portion 5 out of the mouthpiece. The base portion 5 can be re-attached to the mouthpiece by inserting the insert portion (described below) into the receiving area of the mouthpiece and engaging the sealing regions to retain the base portion 5 as inserted within the mouthpiece. Other mechanisms for removably attaching the base portion 5 to the mouthpiece can also be provided. In yet another embodiment, the vaporization assembly 4 may be removably attachable to the base portion 5, for example so as to allow a user to replace the vaporization assembly 4 when no longer serviceable, for cleaning of the vaporization assembly 4, and/or to more readily allow access to a container (e.g. bowl) where a vaporizable product may be loaded into the vaporization assembly 4. For example, the vaporization assembly may be received in a vaporization assembly receiving area 506 (depicted in FIG. 7B) of the base portion 5, and can be attached to the base portion 5 by twisting to engage a chamber bayonet 514 that secures the vaporization assembly in the receiving area 506. The vaporization assembly can be removed by untwisting to release from the chamber bayonet. Other mechanisms for removably attaching the vaporization assembly to the base portion can also be provided. In one embodiment, both the vaporization assembly 4 and the mouthpiece 3 may be removably attachable to the base portion 5. In yet another version, the vaporization assembly 4 may be independently removable from the base portion 5. That is, the vaporization assembly 4 may be configured to be removably attached to the base such that it can be removed therefrom, without requiring that the mouthpiece 3 and/or base portion 5 be removed from one another beforehand. A cross-section view of the device 1 in exploded view can be found in FIG. 3B (FIG. 3A shows a front exploded view).

Referring to FIGS. 4A-4E, an embodiment of the vaporization assembly 4 is shown. Front and cross-sectional views of the structure of the vaporization assembly 4 and a gas flow path therethrough are shown in more details in FIGS. 5A-5B. According to one aspect of this disclosure, the vaporization assembly 4 as shown in FIGS. 4A-4E and 5A-5B is suitable for inhaling a vaporizable substance in the form of an oil and/or wax product comprising the vaporizable substance, e.g., as extracted or otherwise obtained from plant material containing the substance, and may optionally be provided in combination with carriers or other additives. Accordingly, the vaporization assembly 4 comprises a vaporization assembly housing 401, a refillable container 402 configured to receive a vaporizable product within the vaporization assembly housing 401, a heating device 409 configured to be electrically connected to a power source such as a battery and transfer energy to the vaporizable product in the refillable container 402 to heat the vaporizable product and form a vaporized product therefrom, an inlet 403 configured to introduce gas into the refillable container 402, one or more refillable container outlets 404 configured to receive a flow of gas having the vaporized product entrained therein from the refillable container 402, and one or more vaporization assembly outlets 406 configured to provide the flow of gas received from the refillable container outlets to the input opening 510 of the gas flow conduit 505 in the base portion. In one embodiment, the refillable container 402 itself comprises the heating device, such that the refillable container 402 can be directly heated to transfer energy to the vaporizable product therein, and thus no separate heating device is required. For example, sidewalls 418 of the refillable container 402 can comprise a resistive heating element (heater traces, as shown in FIG. 5B via dotted lines) embedded therein, e.g., by wrapping the heating element with soft ceramic material and forming a tube shape, adhering a thin ceramic bottom (without traces) to the tube, then firing the soft ceramic with heating element embedded therein to obtain the refillable container 402. In another embodiment, the bottom of the refillable container 402 may also comprise heating element (heater traces) embedded therein.

In one embodiment, the heating device 409 (heating element or heater trace) is attached to conductive elements such as wires leading to the power source (e.g. battery) in the base portion 5 to provide an applied voltage for the resistive heating. For example, in operation, two wires come from the bottom of the vaporization assembly 4: one of the wires can be held (pressed) between the electrode 417 and the insulator 416, being connected to the heating device 409 embedded in the sidewalls 418, and the other wire can be held between the insulator 416 and the housing 401, traveling up the housing wall and being spot welded to the housing 401. To apply the voltage, the base electrodes 517 contact the vaporization assembly housing 401 and the electrode 417, therefore a current path in and out of the heating device 409 can be created. There can be also grooves cut into the inner surface of the vaporization assembly housing to position these wires.

In yet another embodiment, the heating device is provided separately and/or apart from the container in any suitable form such as a heating plate or coil, and which can be placed in thermal contact with the refillable container 402 at any desirable position/angle such as being disposed below the bottom of the container. For example, the heating device may comprise at least one of a heating plate, a heating ring, and a heating element, and is capable of conductively heating the vaporizable product in the refillable container. As another example, the heating device may comprise an inductively heating device capable of inductively heating the container, and/or may be capable of radiatively heating the container and/or product provided within the container. In one embodiment, the heating element comprises a ceramic heating plate, such as an alumina plate, and may also comprise, e.g. a metal wire, coil, or other element that is capable of resistively heating, and which may also be embedded in a ceramic or glass heating plate or used alone. Additional embodiments of heating elements, heating plates and any other heating structures that can be used to form all or a part of the heating device 409 have been described in U.S. Pat. No. 10,517,334, which is hereby incorporated by reference herein in its entirety.

In yet another embodiment, the inlet 403 and the one or more refillable container outlets 404 of the vaporization assembly 4 are located towards a top of the refillable container 402 and the one or more refillable container outlets 404 of the vaporization assembly 4 are located radially external to the inlet 403 of the refillable container 402.

In one embodiment, the internal gas flow passage 405 is defined between the vaporization assembly housing 401 and walls of the refillable container 402, radially external to the refillable container 402, and the internal gas flow passage 405 redirects the flow of gas received from the one or more refillable container outlets 404 in a direction towards the base portion 5 of the battery powered, removably attachable vaporization module 2. As shown in FIG. 5B, the dashed lines illustrate an exemplary gas flow path within the vaporization assembly 4. A flow of ambient air enters the vaporization assembly 4 through the inlet 403, carries the vapor formed by the heated vaporable product in the refillable container 402, then passes through one or more refillable container outlets 404 located near the top edge of the refillable container 402 and enters into the internal gas flow passage 405, and eventually leaves the vaporization assembly 4 through one or more vaporization assembly outlets 406. In one embodiment, the one or more vaporization assembly outlets 406 is located at a lower region (e.g., the bottom) of the vaporization assembly housing 401. In yet another embodiment, at least one of the one or more vaporization assembly outlets 406 is aligned with the input opening 510 of the gas flow conduit 505 in the base portion 5.

According to embodiments herein, as shown in FIG. 5B, the vaporization assembly 4 can comprise a thermal spacer 410, a securing ring 411, an O-ring 412, a jacket 413, a bowl spacer 414, a washer 415, an insulator 416 and an electrode 417 to conduct electricity to the heating device 409.

Referring to FIGS. 6A-6E, an embodiment of the base portion 5 is shown. A cross-sectional view of the structure of the vaporization assembly 4 and base portion 5 with the gas flow path therethrough is shown in more detail in FIG. 7B. The base portion 5 comprises sidewalls 507 and a bottom wall 508 defining a vaporization assembly receiving area 506 configured to receive the vaporization assembly 4 therein. As shown in FIG. 7B, the base portion 5 may also comprises a chamber air seal 513, a chamber bayonet 514, a chamber detection pogo pin 515, a printed circuit board assembly (PCBA) 516, a base electrode 517, and optionally a battery 518. In one embodiment, the base portion 5 comprises a module housing 501 having an insert portion 502 configured to be at least partly received within the receiving area 306 of the mouthpiece housing, the insert portion 502 having one or more sealing regions 503 configured to form a seal between the module housing 501 and the mouthpiece housing, and a battery receiving area 504 disposed within the insert portion and configured to receive a battery for powering the removably attachable vaporization module 2. Embodiments of the base portion 5 comprise a gas flow conduit 505 having an output opening 509 positioned to output the flow of gas from the removably attachable vaporization module 2 to the receiving area of the mouthpiece at an interior side of the seal 503 between the module housing 501 and the mouthpiece housing. In one embodiment, the gas flow conduit 505 has an input opening 510 formed in the bottom wall 508 of the vaporization assembly receiving area 506 of the base portion 5, and is configured to be directly engaged to and/or aligned with at least one of the one or more vaporization assembly outlets 406 of the vaporization assembly 4 (not shown). An embodiment of the gas flow path is depicted via dashed lines. In yet another embodiment, the gas flow conduit 505 extends from the input opening formed in the bottom wall 508 of the vaporization assembly receiving area 506 to the output opening 509, and as shown in FIGS. 6B and 6C, the output opening 509 of the gas flow conduit 505 is formed on an outer surface 512 of the insert portion 502 of the module housing 501 and is radially external to the input opening 510.

Referring to FIGS. 8A-8E, different views of an embodiment of the mouthpiece 3 is shown. A front view and a cross-sectional view are further provided in FIGS. 9A-9B. According to one embodiment, the mouthpiece 3 comprises a mouthpiece housing 301 at least partly defining an interior chamber 302 having a first end 303 and a second end 304, an inhalation outlet 305 formed in the mouthpiece housing 301 at the first end 303 of the interior chamber 302, and a receiving area 306 for receiving the removably attachable vaporization module 2 that is battery powered, at the second end of the interior chamber 304 within the mouthpiece housing 301. According to embodiments herein, in operation of the portable electronic vaporizing device 1, the flow of gas having the vaporized product entrained therein is passed through the gas flow conduit 505 of the base portion 5 and received into the receiving area 306 of the mouthpiece 3 from the output opening of the gas flow conduit 505, and is passed along the interior chamber 302 of the mouthpiece 3 to the inhalation outlet 305. While the mouthpiece depicted herein is in the shape of a pipe, it should be understood that other mouthpiece shapes and forms are also contemplated herein.

In one embodiment, the battery receiving area 504 of the insert portion is configured to be entirely received within the receiving area 306 of the mouthpiece 3, such that a battery received in the battery receiving area 504 is enclosed by the walls of the mouthpiece 3. In another embodiment, at least a portion of the vaporization assembly 4 connects to the base portion 5 at an exterior side of the seal formed between the module housing 501 and the mouthpiece housing 301. For example, the vaporization assembly 4 may be attached to the base portion 5 at a location that is positioned above the sealing regions 503 that seal the base portion of the removably attachable vaporization module 2 to the mouthpiece, such that the vaporization assembly is located above the mouthpiece. In yet another embodiment, at least a portion of the battery receiving area 504 of the removably attachable vaporization module 2 is configured to be received in the receiving area 306 at an interior side of the seal formed between the module housing 501 and the mouthpiece housing 301. For example, the battery receiving area 504 may be partly or entirely contained within the mouthpiece housing.

Referring to FIGS. 7A-7B and 9A-9B, according to embodiments herein, the one or more sealing regions 503 of the removably attachable vaporization module 2 comprise one or more sealing rings 511 provided about a circumference of an outer surface 512 of the insert portion 502, and which engage an inner surface 307 of the mouthpiece housing 301 in the receiving area 306 to form the seal between the insert portion 502 of the module housing 501 and the inner surface 307 of the mouthpiece housing 301. In yet another embodiment, the seal formed between the module housing 501 and mouthpiece housing 301 at least partly defines the interior chamber 302 of the mouthpiece 3 for flow of the gas having the vaporized product entrained therein from the receiving area 306 to the inhalation outlet 305.

Referring to FIG. 10B, a representative gas flow path within the device 1 is illustrated in a cross-sectional view. A flow of ambient air enters the vaporization assembly 4 through the inlet, carries the vapor formed by the heated vaporable product in the refillable container, then passes through one or more refillable container outlets located near the top edge of the refillable container and enters into the internal gas flow passage, and next leaves the vaporization assembly 4 through one or more vaporization assembly outlets, subsequently passes through the gas flow conduit of the base portion and enters the space between the module housing and the mouthpiece housing, which is also below the one or more sealing regions. The vapor travels along the interior chamber toward the inhalation outlet, and can be inhaled by a user.

In one embodiment, at least a portion of the interior chamber 302 of the mouthpiece 3 is defined by a passage formed between portions of the mouthpiece housing 301 and the surfaces of the insert portion 502. In yet another embodiment, in operation of the device 1, the flow of gas having vaporized product entrained therein is flowed past at least a portion of the battery receiving area 504 of the insert portion 502 before reaching the inhalation outlet 305. For example, as the insert portion comprising the battery receiving area is disposed within the mouthpiece housing, and in between the vaporization assembly and the inhalation outlet, gas exiting the vaporization assembly flows past the battery receiving area of the insert portion as it travels towards the inhalation outlet.

In one embodiment, the output opening 509 of the gas flow conduit 505 is positioned to output the flow of gas from the removably attachable vaporization module to one or more of: (i) a region 308 of the receiving area adjacent the module housing 501, and between the module housing 501 and the mouthpiece housing 301; and (ii) a region 309 of the receiving area below the module housing 501.

In a certain embodiment of the device disclosed herein, the refillable container is disposed above the battery receiving area of the insert portion; the inlet to the refillable container has a diameter of at least 5 mm; and/or the inlet to the refillable container is disposed above the receiving area of the mouthpiece.

In one embodiment, to increase the efficiency of the vaporization, an alternative design of the vaporization assembly can be used. As shown in FIGS. 11A-11E and 12A-12B, the vaporization assembly 4 a has a cap 408 to form a closed space with the refillable container 402. Instead of the relatively wide-open inlet 403, a flow of ambient air enters the vaporization assembly 4 a through a small air inlet 403 a on the cap 408, carries the vapor formed by the heated vaporable product in the refillable container 402, then passes through one or more refillable container outlets 404 located near the top edge of the refillable container 402 and enters into the internal gas flow passage 405, and eventually leaves the vaporization assembly 4 through the gas flow conduit 406. An embodiment of the gas flow path within the vaporization assembly 4 is illustrated in dashed line. A cross-section view of the assembled device 1 equipped with the vaporization assembly 4 a is shown in FIGS. 14A-14B. The gas flow path within the device 1 sequentially passing through the base portion and the mouthpiece is, in certain embodiments essentially the same as illustrated in FIGS. 10A-10B, and therefore is not shown in details.

According to embodiments herein, one or more airtight seals are formed between the base portion 5 and/or the vaporization assembly 4 (4 a) and the mouthpiece 3, so as to create an airtight gas flow path between from the vaporization assembly 4 (4 a), through the gas flow conduit 505 in the base portion 5, and to the mouthpiece 3. In the embodiments as shown, the gas flow conduit 505 in the base portion separates a vaporization assembly internal gas flow path from a mouthpiece internal flow path.

In one embodiment, the vaporization assembly is removably attachable to the base portion via a fastening feature that allows for repeated removal and re-insertion of the vaporization assembly into the base portion. For example, the vaporization assembly may be removable by simply lifting or twisting. In one embodiment, as shown in FIGS. 2 and 3A-3B, the vaporization assembly 4 is attachable/removable by simply inserting into or lifting from the base portion 5. In yet another embodiment, as shown in FIGS. 4A-4E, 5A-5B and 11A-11E, the vaporization assembly 4 (4 a) has a fastening feature 407 that is threaded, and that may be complementary to a threaded socket in the base portion 5, so the vaporization assembly can be screwed into the threaded socket of the base portion. In yet another embodiment the vaporization assembly may connect to the base portion via a magnet, span mechanism or other fastening feature.
